Volcanic Inferno

When your opponent activates a monster effect on the field: You can banish 1 Pyro monster from your GY; inflict 500 damage to your opponent, then, if you banished a “Volcanic” monster to activate this effect, you can negate that effect. During your opponent’s End Phase: You can target up to 2 of your “Volcanic” monsters that are banished and/or in your GY; place them on the bottom of your Deck in any order. You can only use each effect of “Volcanic Inferno” once per turn.
